An old battery charger looks like its the perfect size for the transformer and any other componentsI don’t think that transformer is good for much anymore.Looks old. I saved this label (even though it might not be true anymore)Insides become outsidesTrying to remove the rustTrying to nullify the rust as it might be easier just to take the surface off then paint over.Good stuff

Very old computer PSU has an IEC socket which I can salvage for the power input. Appropriate label below it tooSocket removed, turns out that label was actually the 110v/240v switch covered up. Also found a mains rated switch which might be suitable for the boxRemoved most of the surface rust and old paint with sanders and a wire brush on my drill. Not sure about what kind of paint they used so dust masks are a must.I think this is almost everything. I need. From the left, Electrode holders, cable glands, the original amp meter, a recycled switch, new fuses and fuse holder, recycled IEC socket.I also bought some copper rod for nicer electrodes. This works out to be able 20c per 4cm long electrode. and some extra cabling I will need

The switch fits inside the vertical gap in the front but its a little too long. So I am going to need a faceplate for the switch. using some metal salvaged from the microwaves.Measured and drew out some lines. Cut these with an angle grinder with a cutting blade

After cutting most of the cuts with the angle grinder, I used a hacksaw blade and then a file to tidy up the edges and get that last 0.5 mm edge off so it fits snug.Also need to put this thermal overload protection back in.Make sure it actually still works with it on first (this was a broken microwave)Then re-wrapped it in electrical tape and slotted it back in. I removed the tape from the component to see what it was but I don’t want it shorting on anything
